Kryonaut... holy crap

So when I got my Dell G3 (9300H + 1650), the temps were pretty bad. Scoring ~1900 in Cinebench R20 because of thermal throttling.

I ended up buying some Arctic MX-4 and re-pasting. It didn't seem to help at all. Temps were around the same, benchmark scores were around the same.

Undervolting did help (I undervolted on the stock paste too) and brought temps to just under 100, so it wasn't throttling as much, but still got hot. R20 score went to 2100+

After getting (and returning) a Dell G5 SE, I went back to my G3, and decided to get some Kryonaut, after a discussion in the G5 SE thread.

I just re-pasted with Kryonaut, and it surprised me how much it seems to have helped.

In Cinebench I get around the same scores (2118 on last run) but the fans didn't come on at all until around 1/3 of the way through the test, when the CPU hit 88-89, then the fans kicked in (high performance mode in Dell Power Manager) and it reached 90, but quickly dropped to as low as 84, and tended to hover around 85-87 the entire time. Much lower than the 95-100 it was at before.

All 4 cores at 4Ghz

Sorry there's no "before" screenshots, but I didn't think to take anyway, since I still remembered how it was with stock/MX-4

 

I almost destroyed my XPS 13 9350 with some chinese brand thermal paste. Granted, it was probably dried out, but after ordering some Krynoaut, temps are good!
I did have to order a new battery, which well, it needed a new one anyways. Have you had a chance to try the liquid metal thermal paste?

 

Nah I don't trust myself to apply it properly, wouldn't want to risk it.

Just did a benchmark test in Sleeping Dogs on extreme settings.

GPU maxes out at 69-70C

CPU hits 70C max with turbo boost off, and 70-75C with turbo boost on

Need to test GTA V or something else which will constantly run at 4Ghz

 

Is kryunaut liquid metal or just normal paste?

 

Normal paste.

 

ok. I read that liquid metal is brutal to apply, I guess I am going to give this a shot on my old acer. It's fans kick in alot. Maybe the paste on it is dried up to nothing. Thanks.

 

You need to build up a kind of barrier around the die with electrical tape or normal thermal paste or something. I still worry that it might leak over the tape as the laptop moves around. Also liquid metal can eat destroy heatsinks if they'e aluminium

If it's really old, could just be clogged fans as well. Use compressed air to blow the dust out (put something inside to stop the fans spinning so the bearing doesn't wear out).

MX-4 might work really well for you as well, most people recommend it and it's cheaper per gram. It's just that Kryonaut seemed to help much more for me on the Dell

I still used MX-4 on the GPU just because you get more per tube loll

 

I have used Kryonaut with great success. Liquid Metal is amazing, in the right situation. It is however messy, conductive and ideal for a static application. Kryonaut is really good for most notebook applications.

 

Are you saying with Kryonaut you need to build the dam?

 

Kryonaut is a paste so no dam required. Liquid Metal requires extra care, for a notebook I personally recommend Kryonaut,

 

I believe Liquid Metal is sold under the Conductonaut brand.

 

Conductonaut is Thermal Grizzly's Liquid metal thermal paste, there are many others from other companies. Kryonaut does not need a damn/barrier like a liquid metal would.

 

So in GTA V with Turbo disabled and lowest settings (how I usually play), I get GPU and CPU both below 65C (light fans). It's definitely running cooler than it was before with stock and/or MX-4

With Turbo enabled and lowest settings, I get 70C on the GPU and up to 85C on the CPU

With Turbo enabled and highest settings, I get about the same as on the lowest settings. CPU is a bit lower, mostly below 80C

GPU is using Arctic MX-4, not Kryonaut since I never had issues with the GPU getting too hot with MX-4.

 

No, Kryonaut won't really spill and it's a pretty 'regular' thermal paste, but it seems to be better than your average thermal paste.

If you were to use liquid metal however, I'd definitely recommend a foam barrier to prevent spillage... but if Kryonaut does the trick, stick to that instead.

 

I'm going to try the kryunaut. Thanks.

 

I read somewhere that kryonaut isn't good for longevity, I personnaly use Noctua NT-H2 thermal paste which is a lot better than my MX4 but not as great as liquid metal

 

Grizzly Kryonaut will pump out faster due the thinner and creamy consistency. With laptops worse cooling vs. good desktop cooling this is doomed to happen faster. der8auer is shareholder in Grizzly company and he recommend re-paste after 1 year due mentioned reason. This on desktops who have better coolers/better fits/better pressure/better cold plate.

 

What is carbon based pastes like?

 

Kryonaut on GPU works good aswell, I got a few degrees drop going from MX4 to Kryonaut on laptop gpu

About longevity:
No degradation on one of my laptops after 2 years, same on one of my desktop after a year. However, but systems don't exceed 80C during load, typically stay around 60-75C.

 

I can confirm it works well.

It made a dramatic difference in temps with my xps 15 9560.
